When a computer is turned on the power is supplied to the system and the booting process begins. During this process, the BIOS, which is firmware, checks if all the components of the motherboard are working before initiating the process by loading the MBR information onto the CPU memory. During this process, if the BIOS is unable to access the system memory then the message “Error Loading Operating System” will be displayed. This error can occur due to various scenarios, which we will be talking about further in detail below.
There can be many scenarios due to which the message “Error Loading Operating System” will be displayed. Here is the list of common scenarios when this error can occur and solutions to fix this error on your computer.
During the booting process, the BIOS loads the Operating System which is stored in the Hard Disk onto the CPU memory, but if the BIOS is unable to access the information from the Hard Drive due to corruption or bad sectors then the message “Error Loading Operating System” will be displayed.

If you haven’t found any errors in your Hard Drive and are still unable to load your OS even though your Hard Drive is working fine, you can proceed to the next step.
A master boot record (MBR) is a special type of sector in the boot at the very beginning of the partition, which loads the Operating System onto the memory within seconds. However, if the MBR folder becomes corrupted the message “Error Loading Operating System” will be displayed.

If this didn’t fix the error then there is no corruption with your MBR, you should proceed to the next step.
When Multiple hard drives are connected to your computer and the primary hard drive which has the operating system is not sequenced then the message “Error Loading Operating System” will be displayed. If multiple hard drives are connected to your system, you need to ensure that the hard drive which has your Operating System is sequenced in the boot.
Note: Every manufacturer has their own set of keys to get into BIOS, visit the manufacturer’s website to get the Key
If this was unable to fix this error then there might be a problem with your BIOS, please proceed to the next step.
In rare cases, the lack of an update could cause compatibility issues with newer operating systems or performance issues. Generally, you won’t have any issue with the BIOS but in rare cases, some problems do occur and those few updates show up.
Note: You should always take extra care while updating your system BIOS, if you face any power failure or system crash during the upgrade process you will end up corrupting BIOS firmware.
If this couldn’t fix the error then there can be some problem with your Operating System files, please proceed to the next step to resolve the issue.
